January 1999 lunar eclipse

From Wikipedia, the free encyclopedia

A penumbral lunar eclipse took place on Sunday, January 31, 1999, the first of two lunar eclipses in 1999.

This was a relatively rare total penumbral lunar eclipse with the moon passing entirely within the penumbral shadow without entering the darker umbral shadow.[1]
